ENVELOP.

Specification of Letters Patent.

Patented Jan. 13, 1920.

Application filed January 3, 1919. Serial at. 269,431.

To all whom it may concern:

Be it known that 1, WILLIAM W. L. AHANA, a citizen of the United States,residing at Honolulu in the county of Oahu and Territory of I-Iawaii,have invented new and useful Improvements in Envelops, of which thefollowing is a specification.

This invention relates to envelope, and particularly to openerstherefor.

The object of the invention is to provide an opener comprising asevering strand extending along one of the fold lines of the envelo andconnected ,at one end with a 'partia y separated portion of the envelopforming a tab, said'tab serving as a grip whereby the thread may begrasped and manipulated to uickly and conveniently fever the envelop aong the determined fold A further object of the invention is to providea novel form of tab and mode of connecting the severing strandtherewith,

whereby the manipulating end of the strand will be held securely againstcasual displacement, and whereby the same may be firmly gripped and heldfor the severin' action.

The invention consists of the eatures of construction, combination andarrangement of parts hereinafter fully described and claimed, referencebeing had to the accompanying drawing, in which Flgure 1 is a back viewof one form of envelop embodying my invention, showing the sealing flapclosed.

Fig. 2 is a similar view, showing the tab turned out so as to be grippedfor the openini actlon.

1g. 3 is a view similar to Fi 1 and 2, showmg the sealing flap unsea edand in open position.

In the present instance I have shown the a plication of the invention toan envelop o 'oblong rectan ar form, comprisin a front 1 and a beeformed of a bottom ap 2, end flaps 3, and a gummed top sealin flap 4,the flaps 2 and 3 being united an formin with the front 1 the envelowhich 1s adapted to be sealed by olding the flap 4 over upon andsecuring the" same by its gummed-margin to the flaps 2 and 3. It is,however, to be understood that the inbody vention may be applied to anyother form of envelop in connection with which it may be used.

A severing strand 5, composed of cord or wire, is provided for severingthe envelop along one of its lines of fold. This strand is glued orotherwise fastened to the envelop along th line of fold. In the presentinstance I have shown the strand 5 extended along the line of foldbetween the front 1 and flap 4 for cooperation with an ungummed tab 6formed as a part of said flap,

but it is to be understood that the tab may be formed as part of any ofthe other flaps and the strand 5 arranged along the fold line betweensuch flap and the front 1.

The tab 6 is of suitable shape and size to enable it to be firmlygripped between the thumb and forefinger. It is formed at one end of thedesignated flap, as the flap d, and partially separated at its inner endtherefrom'by a (preferably V-shaped) notch 7;

The notch 7 extends from the free edge of the flap toward its fold line.but terminates short of the fold line so as to leave a narrow intactportion 8 between such fold line and the contracted end of the notch.The tab is thus normally held to lie in the plane of the fla 4 but maybe turned outward and upwar from the plane of the sealed flap 4,

as shown in Fig. 2, into the plane of the i front 1, in which operationthe portion 8 is severed to entirely separate the tab 6 from the flap 4preparatory to tearing away said tab from the front 1 and separating thefront 1 and tab 4 along the intervening fold line 9.

The strand 5' has an end portlon 10 arranged in looped formation andcemented to the underside of the tab 6, thus securing maximum stren h ofconnection and providing a lurahty. of surfaces whichtmaybe grippe bythe operator to enable a firm grip to be obtained. It will thus beunderstood that the operator may secure a firm gri upon the tab and oneend ofthe strand an in an obvious manner may tear the same free from theenvelop and quickly and conveniently'rip the envelop open along the foldline 9. Also it will be evident that the structure is simple and may beapplied to various types of envelops without materially adding to thecost of manufacture thereof.

Having thus fully described my invention, I claim a An envelopcomprising a body having the usual inturned flaps constituting the backof the body, one of said flaps near its extremity and the line of foldthereof being cut from its edge inwardly to a point near the line offold to form a tab integral with and removable from the said flap, acord within the body and extending along the line of fold of the saidout flap, and the end of said. 00rd being glued to the underface of thesaid tab.

In testimony whereof I affix my signature.

WILLIAM W. L, AHANA.
